CODEC FOR DIGITAL ANSWERING PHONE
S5T8554B03
INTRODUCTION
The S5T8554B03 consists of on-chip PCM encoders, decoders (PCM CODECs)
and PCM line filter. This device provides all the functions required to
interface a full-duplex voice telephone circuit, digital answering phone. This
device is designed to perform the transmit encoding and receive decoding as
well as the transmit and receive filtering function in PCM system. Also it is inten-
ded to be used at the analog termination of a PCM line / trunk. This device
provide the Band pass filtering of the analog signals prior to encoding and
after decoding. This combination device performs the encoding and decoding
of voice and call progress tones as well as the signaling and supervision
information.
